PATENT @ltWlltt JAY-SON E. GILLESPIE, F NORMAL, NEBRASKA.

OIL-TUBE STRAINER.

Application led February 2, 1925.

This invention relates to a strainer for the funnel of an oil tube of the Ford type of motor, the general object of the invention being to provide means for preventing particles of carbon and other foreign matter, contained in the oil in the fly wheel housing, from entering the funnel and returning with the oil to the crank case.

Another object of the invention is to make the device adjustable so that it can be made to fit different sizes of funnels.

This invention Valso consists in certain other features of construction and in the combination and arrangement of the several trated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or `corresponding parts throughout the several views, and in which Y Figure l is a sectional view through a: portion of a motor vehicle showing the invention in use.

Figure 2 is an enlarged view, partly broken away, of a funnel with the invention applied thereto. I

Figure 3 is a section on line 3--3V of Figure 2.

Figure l is a perspective view of one form of the device.

Figure 5 is a view'of anotherl form of the device.l v

As is well known a funnel l is placed in the fly wheel housing A of certain types of internal combustion motors for catching the oil thrown up by the flywheel and directing 40 it into the oil tube 2 which returns it to the front end of the crank case. This funnel is formed with a bracket 3 whichA is fastened to a wall of the housing by a fastener which vpasses through the hole 4; in the bracket. Illhe entire curved` side of the funnel is open -so that particles of carbon and other foreign matter contained in the oil4 will pass into the funnel and into the tube. These particles often choke the tube and interfere with the proper lubrication of the motor and it is the object of my invention to provide parts to be hereinafter fully described, illus-- Serial No. 6,489.

vupper end of the funnel and the plate 7 is provided with a pair of holes 7 through which a wire 8 is passed and then the wire is fastened around the lower end of the funnel. AThus the screen is fastened to the funnel and the bars cover the open side of the funnel with small spaces between the bars and the side walls of the funnel .so that the oil is screened as it enters the funnel.

In order to make the device tit different sizes of funnels l cut the bars at their centers, as shown at 9, and insert in each bar a rod l0 so that the two halves of each bar can be separated and thus the device made longer. After the device is made of the proper length the parts can be soldered or otherwise fastened together.

From the foregoing it will be seen that I have provided a simple device for preventingforeign matter from entering the funnel of an oil tube of an internal combustion motor so as to prevent the tube from being choked and for keeping the oil in the crank case free from particles of foreign matter.

lt is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

l desire it to be understood that I may make changes in the construction and in the combination andV arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

A strainer for the funnel of an oil tube of an internal combustion motor comprising a pair of spaced curved bars, a cap'to which the upper ends of the bars are connected, said cap having a flange fitting over the upper end of the funnel and a plate to which the lower ends of the bars are connected, said plate having holes therein for receiving fastening means for connecting it with the lower part of the funnel.

ln testimony whereof l aiiix my signature.
